Paul Cassidy
Founder and President
Paul’s passion for water and fishing is evident as soon as you walk into his office. Trophy size fish cover the walls and he’s got a unique story for each of his catches. Paul brings this passion and love for the sport to work each day, whether it involves fish or not. His eleven years of experience as the Northwest Area Fisheries Manager for the New Mexico Department of Game and Fish doesn’t hurt either. Paul’s influence and expertise shines through in each and every lake and stream built by ACI. Although Paul primarily takes on the marketing and client relations duties for the Company, there isn’t a design or proposal that goes out the door that doesn’t first get his stamp of approval.
